This invention relates to an improved construction of safety catch, and has for its ob- 'ect to provide a, new method of forming the ody portionof the catch of'a single piece of metal havin a pair of side'ears connected through a shan portion toand bent up from a common baseortion,the ears being enlarged to provide bearings for the rotor trunnions and th'e'shank portions'being provided with integral stiffening ribs which are widely separated by, the stretching ofthe stock of the base during a folding operation of the. ears upward therefrom, the ribs serving a double purpose of stifiening the shank portions and also providing an enlarged attaching area for the base. With these and other objects in view, the invention'consists of certain novel features of construction,- as will be more :fully described, and particularly pointed out in the appended claims. I i

In the accompanyin drawings:

an end view of the body porbearing for the elongated trunnion on the rotor and also to provide a protecting'hous ing for the point of the pin-stem and ,to connect both ofthese ears to the base portion" of the body by a relatively thin shank so as 'to reduce the'amount, to-the minimum, of the precious metal of which the body. is.

V ly made and toalso form integral with these shank portions stiiieiiing ribs, which nsua r ibs also serve toprovide extending support mg base when spread into operating position by the method" of folding up thei'ear. portions from the base, by which-operation the spread or. widely separated position enlar es the su porting area of the base'of the b0 y: and t e following is a detailed description of the present embodiment of my invention showing one'construction by which these advantageous I results may be accomplished:-

With reference as gold or. silver and, therefore, is so deto the drawings, 10 desig nates the body of the catch which is swaged of metal, usually of the precious metals, such maximum strength for performing its im- 1.

" thickness than; the I ear 11- and is provided withla relatively deep bearing portion for resently dearin openbody fine'mbeiis being-bentup to form the base-portion16,as illustrated in Figure 4, by being bent up over-the anvil or former 17 shown in dottedlinea' is caused to spread andfso separate these rib members 15 one ifrom the other, thus roviding an extended baseiportion, as-best i lustrated in Figure 8, in 'w ich the ribs are shown as providlng an extended support for soldering or otherwise attachin this baseto the back of the bar pin 9. gVhen' the body of the catch is bent up into position as illustrated in Figure 5, a spacev 18 is provided in-which the rotor disc'member' 19 is mounted and this body is provided with an elon ated radially-disposed slot 20 through bot of its ears, which is adapted to receive the pointed end of the pin-stem 21, the elongated ear 12 serving a double purpose, first, that of providing an elongated bearing 13 for the trunnion, and second, the slot in this ear 12 is for housing the pointed end of the pin-stem so that this point will not project beyond the end of this ear to catch in the fabric of the garment to which the same is attached.

The rotor 19 is preferably formed in disc shape and is provided with an elongated trunnion 21 to be inserted into the bearing 13 and a shorter trunnion 22 to be inserted into the bearing 14 of the body. This rotor is also rovided with a radially-disposed slot 24 w ich extends down through its trunnions 21 and 22 about the center thereof and is also provided with an operating arm 25 set at substantially 70 back from the central line through the radial slot and also is rovided with a second arm 26 widely spaced om the arm 25 and set at a distance substantially 75 back from the arm 25.

These arms are so arranged that when the rotor is in open position the arm 26 engages the base 16 of the body, which serves as a stop when the two radial slots register and the arm 25 is caused to engage the base on the opposite side, to form a stop when the rotor is in its complete closed position. In both these instances when the rotor is in either its wide-open or entirely-closed position, neither of the arms 25 or 26 extends above the top-of the body portion so as to prevent these arms from engaging in the adacent fabric of the wearer.

Having thus described one illustrative embodiment of my invention and the best mode known to me for carrying out my method, I

desire it to be understood that althoughspecific terms are employed, they are used in a generic and descriptive sense and not for the purpose of limitation, the sco e of the invention being defined and limite only by the terms of appended claims.

I claim:

1. An improved method of forming a body member for safety catches, which'consists in swaging the same from sheet stock to provide a pair of ear members connected by a shank to a base portion and having a r1b on each shank. portion, and bending the ears and shanks upward and simultaneously stretching the base portion to separate the ribs whereby the lower ends of said ribs serve to enlarge the area of the supporting baseof the body.

2. An improved method of forming a body member for safety catches, which consists in swaging the same from sheet. stock to provide a pair of ear members connected by a shank to a base portion and having integral stiffening ribs oneach shank portion, one of said ears being swaged deeper than the other and both being recessed to receive the keeper trunnions, bending the ears and shanks upward from the base and simultaneously stretching the base portion over an arbor, reducing the thickness of the stock and separating the ribs whereby their lower ends serve to enlar e the area of the supporting base of the ody.

8. An improved method of forming a body member for safety-catches, which consists in swaging the same from sheet stock to provide a pair of ear members connected by a shank to a base portion both being recessed to receive the keeper trunnions and said shank having a channel forced therein with the stock extending outward to provide an integral stitfenin' rib, bending the ears and shanks upward rom the base and simultaneously stretching the base portion over an arbor to reduce the thickness of the base stock and separate the ribs whereby their lower ends serve to enlarge the area of the supporting base of the body.

In testimony whereof I afiix my signature.
